Remove trailing whitespace
Change makefile to use variable for directories (SRC_DIR/BASEDIR)

For easier maintainance.
Change case of files and add targets so it builds on Linux

Needed to change some paths from ../ to ../../, change case of a few files,
add waveram.c and add _VERSION2 define.

It compiles successfully on Linux now :-)
